WASHING- CHhllE.

- Application filed December 13, 1923. aerial No. 680,35*?.

To all whom 'it may concern.

Be it known that l, MAX BRANDT, a citizen of the United States, residing at laos Angeles, in the county of Los An eles and State of California have invente certain new and useful lmprovements in Washing Machines, of which the following is a specification. l

ll/ly invention relates generally to laundering appliances and more particularly to an apparatus that may be readily applied to an `ordinary bath tub to form an efficient and practical washing machine.

'lhe principal objects of my invention are, to provide'aV household laundering apparatus that is of relatively simple structure,

rcapable. of being easily and cheaply produced and constructed so as 'to be readily applied to or removed from an ordinary bath tub; to provide a laundering 'apparatus of the character described that may, be lfolded up and packed into a relatively small space while not in use and further, to' provide a household laundering appliance that is actuated by a small electric motor, whereby the launderingoperation may be quickly and economically accomplished without any edort on the part `of the operator, other th the transfer of the laundered articles from the tub to the wringer that is associated with and forms a part of my improved washing machine.`

With the foregoing and other objects in view., my invention consists in vcertain novel features of construction and arrangement of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which:

Fi 1 is a plan view of my improved laun ering apparatus in position upon a hath tub.

Fig. 2 is a vertical section taken on the line 2--2 of'Fig; 1.

Fig. 3 is an elevational View of the parts seen looking in the direction indicated by the arrow 3 in Fig. 2.

Fig. 4L is an enlarged detail section taken i through the center of the bath tub or cover and showing the clothes rack vsupporting bath tub having the usual hot and cold water connections 11 and the dane 12.

ll apparatus includes a lid or cover upper marginal plate 13, preferably formed of sheet metal l@ andof size and shape Vas to entirely cover' the tub 10.

Arranged on the under side of this lid or cover and at its edge is a gasket 1l, pref-` erably formed of rubber that is adapted to 65 lie directly on top of flange 12 and produce a substantially water tight joint.

' Secured on top of lid 13, near its ends are transversely disposed 'l bars 15 and 16 the ends thereof projecting slightly beyon 70 the side edges of lid 13 and passing through apertures in said projecting ends, are the Shanks of hooks 17 that are adapted to engage beneath flange 12 of the tub.

` 'lhe upper portions of the Shanks of these 75 hooks 17 are threaded and receive winged nutsand said hooks and nuts provide means for) very firmly securing the lid on the bath tu v when a@ iid is applied a uw ab, access a may be had to the faucets F through a hand hole 19, that is normally closed bya removable plate 20 and the latter being provided with suitable clamping means.

lFormed in lid 13 near the cross bar 16 a5 is a relatively large opening 21 through which the articles to be laundered may readily pass and this opening is normally closed b a readily removable plate 22, having suitable fastening means.

A. horizontally disposed clothes-carryin rack 23 of wire mesh or suitable reticulate material is arranged to reciprocate vertically within bath tub .10, the ends of said rack bearing on vertical guide rods 2l that 95 depend from lid 13.

Secured on top of the center of this rack 23 is a socket 25 that receives the lower end @i null of a vertically reciprocating rod 26, the upper portion oit which passes through an aperture 27 in the center of lid 13.

rllhe lower end of rod 26 is detachably secured to socket 25, by means of two pins or bolts 28 that pass through suitably formed apertures in said rod and socket. The arrangement just described permits the pins or bolts 28 to be manipulated, so that when the raclr 23 is litted into position imnie diately beneath lid 13, and socket 25 projects through aperture 27, the rod 26 may be folded or swung downward into -a hori Zent-al position directly on top of lid 13 as illustrated in Fig. 4l.

Thisprocedure is carried out when. the apparatus is removed from the tub or packed `for storage or transportation.

Detachably secured to 'll bar i6 is the lower end ot' a wringer trame 29, in which is arranged for rotation a pair oi wringing rolls 30, that are geared together by pinions 3l.

Arranged on a support 32 at one end oft frame 29 is a small electric motor 33, the

shaft of which is extended and has bear-k ing on said trame and loosely mounted on4 the extended portion of said shaft is a pinion 35 and a gear wheel 36, the latter meshing with the upper one of the pinions 3l.

Pinion 35 meshes with a gear wheel 37 that is loosely arranged on the shaft of the upper one oi"- the wringer rolls.

rlhe hubs of pinion 35 and gear wheel 36 are provided with suitable clutch faces that are adapted to be engaged by corresponding clutch faces that are formed on the ends of a collar 36 and which latter is arranged to rotate with and slide lengthwise upon the motor shaft between the hubs of said pinion 35 and gear wheel 36.

Clutch collar 38 is arranged to he shifted from one position to another by a small hand lever 39 that is ulcruined on a bracket ILO.

dournalled in bearings that project outward from the sides ot the wringer frame 29 is a rock shaft al and projecting outwardly from the center thereoil is an arm 42, the outer end of which is connected by a linlr 43 'to the upper end of rod 26,

An arm r4 projects from one end oi' the rock shaft al along side of gear wheel 37 and passing through a slot'l lin said arm and seated in said gear wheel is a wrist pin 4&6.

si brace 47 is secured to the end of the lid 13, adjacent to the Llbar 16, the upper end of said brace being connected to *the upper central portion of frame 29 and the lower end of said brace being adapted to r'est on the loor.

lin the operation of my improved washing machine lid or cover 13 is placed on top of the bath tub and secured thereto by proper 'lessees clutch collar 38 into engagement with l hub of pinion 35.

As motor 30 is started the shaft thereof drives clutch collar 33 that is engaged wili pinion 35 and the latter drives gear wheel 37 that runs idly on the shaft oi" the upper wringer rollc Ais gear wheel 3'? is thus rotated, arm having a slot and pin connection with s gear wheel will be vibrated vertically, theren by rocking shaft al, and consequently swing ing arm l2 through vertical plane.

As a result o these movements, racll will be vreciprocated vertically and the clothes carried by said rack will con` stantly agitated in the wash water, thereby accomplishing the cleansing operations in a relatively short time.

After the articles have thus been laundered, clutch collar 38 is moved to a neutral. position so as to stop the clothes raclr vibrating mechanism and after detaching plate 22 the laundered articles are removed through opening 2l and lifted so to be engaged by and pass through the wringer rolls 30.

rlhese wringer rolls are driven by shifting clutch 38 into engagement with the hub oi2 gear wheel 36 and, as the latter is rotated, its motion is transmitted through pinions 30, to said rolls.

By removing the raclr 23, rod 26 fA wringer frame 29 from the lid and securing the latter in position on the tub a convenient bath cabinet is provided, whereby a person may take Va steam or medicated vapor bath and in such case, the person using the 'tub fil enters and leaves the same through. the opening 2l.

'lhus it will be seen that l have provided` a relatively simple and practical apparatus that may be applied to an ordinary bath to form a convenient and effective household washing machine.

Obviously minor details in the size, form and construction of the various parts ot my improved laundering apparatus may be tral portion of said cover depending guide rods tions of said a there heing a normally formed in that portion of said cover that is positioned. over the faucets of the a normally closed opening bath tub, and formed in said cover plate l0 receiving rack, a post secu from said cover plate,
